Hello, Could someone help me get the record matching rules set up? I can't find instructions in the documentation, and the ones that are in there already don't seem to work. We usually use the OCLC accession number as match points, so I tried this (basically a guess): Description - OCLC control number Threshold - 1000 Search index: o Score: 1000 Tag: 020 Subfield: a Offset: 0 Length: 9 I also tried making the offset "ocm" since that is the prefix before the OCLC number, which is 9 digits. These were total guesses, but I wanted to at least show you what I'd tried! Thanks. Karen Kohn Collection Development Manager Landman Library Arcadia University 450 S.
